The beauty of the WSSM series is that they run great in the AR-15 platform as they are an inch shorter.I thought ar 10s chamber anything based off of a 308!
The cartridges in this family are, in order of development:
Name | Year | Bullet diameter | Notes |
---|---|---|---|
.223 WSSM | 2002 | .224 in. (5.69 mm) | performance similar to .220 Swift and 22-250 |
.243 WSSM | 2003 | .243 in. (6.17 mm) | performance similar to 6 mm Remington and .243 winchester |
.25 WSSM | 2004 | .257 in. (6.53 mm) | performance similar to .257 Roberts and .25-06 Remington |
6.5 WSSM |
The rounds can be loaded much higher velocities than this chart. Like earlier said, the factory WSSM rounds are about 100 fps faster than long action bolt guns. Reloads much faster.
New powders developed for short fat cartridges like RL-17 up the speed while retaining safe pressures.
